Abstract: The rodent community structures and the biomass changes of the 5 types of vegetation successions were studied in Huangnihe forest region,Jilin Province from June to september,1988.After the cutting of the conifer-broadleaf mixed forests,the number of the Clethrionomys rufocanus increased while that of the Apodemus peninsulae decreased and the Apodemus agrarius invaded.After the formation of the secondary broadleaf forests and artificial larch forests,the rodent communitY was still the type of Agodemua peninsulae+Clethrlonomys rufocanus.The forming of the artificial Korean pine forests Made the number of the Clethrionomys rufocanus decrease apparently. and the Apodemus peninsulae community came into being accordingly .The forests were cultivated into farmlands,hence the formation of the Apodemus agrarius+Apodemus pentnauiae community.The grassy marshlands developed into grassy marshland forests .The rodent community was evolved into Clethrionomys rufocanus community from Microtus fortia+Clethrlonomys rafocanus community.The influences of environmental elements upon the rodent successions were also analysed in this paper.

摘要: 本文研究了吉林省黄泥河林区5个次生植被类型的鼠类群落结构和生物量的变化。原始针阔混交林采伐后,大林姬鼠数量减少,棕背鼠平数量增加,黑线姬鼠侵入。形成次生阔叶林和人工落叶松林后,鼠类群落仍为原始针阔混交林中的大林姬鼠+棕背鼠平群落类型。人工红松林的形成使棕背鼠平数量明显减少,成为大林姬鼠群落。森林开垦成农田,相应形成黑线姬鼠+大林姬鼠群落。草甸发展成草甸森林,鼠类群落由东方田鼠+棕背鼠平演变成棕背鼠平群落。并分析了环境因素对鼠类演替的影响。
